Silicon Valley mainstays and startups like  Google  and  Dropbox  are hiring tons of interns for this coming summer, the  Wall Street Journal Reports . Dropbox plans to hire three times as many interns for this summer as for last summer. This would make interns one whole third of Dropbox's entire engineering team. Bump Technologies , maker of the popular bump-to-share-your-contact-info app, plans to hire ten interns this coming summer. These interns will make up a pretty large chunk of Bump's 30 employee office. Facebook  plans to hire 625 interns for this coming summer, while Google plans to hire more than a thousand youngsters for summer jobs. So why all the hiring up? Finding and keeping full-time hires is tough enough at a tech company because of rampant poaching, so these companies have been increasingly turning to college students for first-year employees. Most of these companies offer interns around $10,000 for a summer-long gig.
